Question 3 of 5
Which one of the following bones is not part of the Axial Skeleton?
Correct Answer: C
Rationale: The axial skeleton includes the skull, vertebral column (vertebrae), sternum, and ribs, forming the body’s central axis. The ulna, a forearm bone, is part of the appendicular skeleton (limbs and girdles), making 'Ulna' the correct answer for what is not axial.
Question 4 of 5
Which one of the following are the two bones located in the forearm?
Correct Answer: D
Rationale: The forearm contains two bones: the radius (lateral) and ulna (medial). Scapula and clavicle are pectoral girdle, cranium and sternum are axial, and tarsals/carpals are ankle/wrist, making 'Radius and Ulna' correct.
Question 5 of 5
The skull is what type of joint?
Correct Answer: B
Rationale: The skull’s joints are sutures, fibrous and fixed (immovable) in adults, locking cranial bones. Sliding (gliding) and synovial are movable, and slightly movable doesn’t fit, making 'Fixed Joints' correct.
